Both the engraver and precision tip can be found in my store here... Chomas Creations toolshttp://www.amychomas.com/index.php?main_page=index&cPath=9&zenid=7mocrdl9en7dl5v375ts1bugj6
These blanks are only around 1/2 inch in diameter, so they are very small!
Here are both of the tips with some less detailed images and you can see that they pretty much look the same. It does seem that the precision tip did etch a bit deeper.
Here is the precision tip in the Silhouette machine. If you look on any of the images you can see an etched line below the lip on both the engraver and precision tip. I have put this in my machine at this line instead of at the lip to prevent any scratching of the raised surface. If you have a thicker item to engrave on I highly suggest it.
Like what you see? Leave a comment to let me know! Thanks Amy Chomas
